Dear Pro Mod Wad,

I want to put a 125 HP system on my car. The intake and carb are Dominator. Can I use a Dominator plate with the 125 Power Shot system? The reason why I ask is that I have two 125 systems. I do have a Cheater system but no plate. Would I do better to use it with a Dominator plate?

Thanks very much,

— Dennis

 

Dennis,

Make your life simple. Call NOS and order part number 12600 Dominator Cheater plate kit. It comes with plate, jets and plumbing from solenoids. You can also order two extra jet sizes .47 for N20 and .55 fuel. This will allow you to put your Cheater system in operation with the 125 HP you are looking for. The two Power Shot systems you have can probably be sold at a swap meet or to friends.

Thanks for writing.

Sincerely,

— Pro Mod Wad

 

Dear Pro Mod Wad,

I really enjoy watching the Pro Mod class (usually on TV, as we don’t have too many Pro Mods in Arizona.) The nitrous cars really astonish me with the speeds and e.t.’s they can run.

My question is how quick and fast do you see Pro Mods running in the coming season? Is 6-teens at 225 in the picture? Would it be possible sometime in the future to see one of these cars run in the 5’s? Say five years or so? Also, I am somewhat surprised that the Super Eliminator Nitrous dragsters have not run in the 5’s yet. I’d be interested in hearing your comments on that.

Thanks for taking the time to read my letter. I go back a long time in drag racing. I see nitrous cars of today kind of like the A/GS and Top Gas Dragsters of years ago.

Cliff,

Great question! To answer the second part first, the S/E class had one 5- second run at Budds Creek, MD. This year in qualifying, Neal Parker with a blown BBC roadster ran a 5.96 at 227 mph. That run was never backed up to become a record.

As far as nitrous S/E cars, the quickest run so far is by Dave Price in the Wirtgen America dragster at 6.13. Unfortunately, I don’t think you will see a 5-second nitrous car in S/E or Pro Outlaw as it is now called (Big mistake!) because the class is becoming a blower-only class due to the poorly written (blower friendly) rules.

Back to the first part of your question concerning Pro Mod cars. I wish I could see that far into the future! My personal opinion on a five second pass for nitrous Pro Mod is No, not in my lifetime anyway. Teens maybe, 225 definitely as we have one or two cars that are almost there. Tommy Mauney and Dale Brunsfield are just touching the 225 zone.

Some info for you: Save the weekend of Feb. 18-20 of 2000 for Speed World Raceway in your area. There will be a Pro Mod Shootout that weekend and you can get right up close. If you see me cruising the pits, please say Hi. Thanks for the letter, Cliff.

Sincerely,

Pro Mod Wad:

I am running a BBC 505 c.i. with a fogger system. I would like to know if I can use "staggered jets" in the fuel/nitrous tune ups and still use the same flow procedure? For instance, I normally use 32’s squared; can I go 34 nitrous and 32 fuel and still keep the same fuel pressure? If not, how do I figure the right pressure?

— Charlie

 

Hi Charlie,

The answer to your question is yes, you can use the same fuel pressure when stagger getting — providing you are not moving in large amounts. If you are following our tuning suggestions then you’re on the "safe" side as far as N2O/fuel ratios. By reading your plugs you can get a better idea of necessary changes in your pressure settings.

If you decide to change total patterns and move up more than 2 lbs. with N2O/fuel, then you should increase your fuel pressure by 1/8 to 1/4 lb. Again, check your plugs for rich/lean conditions for the final tune up.
